EP20K100CQ208C9 概要

The Intel (formerly Altera) EP20K100CQ208C9 is a member of the APEX 20K family of field-programmable gate arrays (FPGAs), delivering 100,000 typical gates and 4,160 logic elements (LEs) in a 208-pin PowerQuad QFP package. It integrates 53,248 RAM bits, four phase-locked loops (PLLs), and 159 user I/O pins, supporting 0.18-micron CMOS SRAM-based logic fabric with embedded system-on-a-chip (SoC) capability.

An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement any digital logic function. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> SoC FPGAs, and are widely used as alternatives to application-specific integrated circuits (ASICs) for prototyping, low-volume production, and high-performance parallel processing tasks such as DSP, communications, and custom compute accelerators.

Key features of the EP20K100CQ208C9 include 4,160 logic elements, 26 embedded system blocks (ESBs) delivering 53,248 RAM bits, four PLLs for clock management, and a maximum of 159 user I/O. The device operates across commercial 0 to 70 C temperature range (the C9 speed grade) and supports in-system programmability via the IEEE 1149.1 JTAG interface and the Altera Passive Serial configuration scheme. The APEX 20K architecture combines look-up table (LUT) logic with embedded memory, enabling designers to integrate glue logic, FIFOs, and small register files on a single device.

Architecturally, the EP20K100CQ208C9 uses a MultiCore architecture introduced by Altera in 1999, distributing MegaLAB structures across the die and providing dedicated high-speed interconnect (FastTrack) for predictable timing. The four PLLs support clock multiplication, division, phase shifting, and frequency synthesis, simplifying board-level clock tree design for synchronous logic and source-synchronous interfaces.

Typical applications for the EP20K100CQ208C9 include telecommunications line cards, custom peripheral controllers for industrial automation, glue logic replacement for legacy ASICs, prototype validation of ASIC designs, PCI bridge implementations, and digital signal processing front-ends. The 208-pin PQFP package is well-suited for through-hole and socketed designs where rework and field replacement are valued over board density.

When designing with the EP20K100CQ208C9, engineers should use the Altera Quartus II (legacy) or MAX+PLUS II development environment for synthesis, place-and-route, and timing analysis. Configuration data must be loaded from a serial EEPROM or downloaded via JTAG; ensure your board supports the Passive Serial configuration mode and provides proper MSEL pin strapping for the chosen mode.

This page synthesizes distributor stock levels, drop-in same-package alternatives from the APEX 20K family, and practical design notes that go beyond the manufacturer datasheet, helping engineers evaluate the EP20K100CQ208C9 against modern FPGA alternatives.

What family does the EP20K100CQ208C9 belong to?

The EP20K100CQ208C9 belongs to Intel's (formerly Altera) APEX 20K family of SRAM-based FPGAs. It uses the MultiCore architecture with MegaLAB structures and delivers 100,000 typical gates with 4,160 logic elements and 26 embedded system blocks (ESBs) totaling 53,248 RAM bits in a 208-pin PQFP package.

How many user I/O pins does the EP20K100CQ208C9 have?

The EP20K100CQ208C9 provides up to 159 user I/O pins in its 208-pin PowerQuad QFP package, with 49 pins allocated to power, ground, JTAG, configuration, and dedicated clock inputs. The actual usable I/O count is 159 according to the manufacturer datasheet, suitable for mid-density parallel interfaces.

Is the EP20K100CQ208C9 still in production?

No, the EP20K100CQ208C9 is marked obsolete by Altera (now Intel). The APEX 20K family was discontinued in the mid-2000s and replaced by Stratix and Cyclone families. New units are available only from distributor excess stock and the secondary market - check stock with DigiKey, OEMstron, and authorized brokers before designing in.

Where can I buy the EP20K100CQ208C9 today?

According to distributor data current as of 2026-09-07, the EP20K100CQ208C9 is available from DigiKey (Altera listing), OEMstron, Ariat-Tech, Veswin, Jotrin, and Micro-Semiconductor.com. Lead times vary because the part is obsolete; expect 4-12 weeks for orders from broker inventory. Always confirm RoHS status before placing volume orders.

What is the price of the EP20K100CQ208C9 in 2026?

Pricing for the EP20K100CQ208C9 as of 2026-09-07 sits around $42.50 at qty 1, scaling down to roughly $25.10 at qty 1,000 across distributor listings. Obsolete Altera parts typically command 3-10x their original 2002-era MSRP because supply is constrained. Request quotes from multiple brokers for competitive pricing.

What is the difference between EP20K100CQ208C9 and EP20K100CQ208C8?

The EP20K100CQ208C9 is a faster speed grade than the C8 variant; the lower number suffix (C9 vs C8) indicates a tighter timing specification. Both share the identical 208-pin PQFP package and 100K-gate die, so they are pin-compatible drop-in replacements for each other on the same PCB footprint. Choose C9 for higher clock rate designs.

Can the EP20K100CQ208C8 replace the EP20K100CQ208C9 directly?

Yes, the EP20K100CQ208C8 is a pin-compatible drop-in replacement for the EP20K100CQ208C9 in the same 208-pin PQFP package, but with a slower speed grade. Designers should re-run static timing analysis after substitution because the C8 part will not meet C9 hold-time margins in designs that target maximum clock rates near the C9 specification.

What software do I use to program the EP20K100CQ208C9?

The EP20K100CQ208C9 is programmed using Altera MAX+PLUS II or Quartus II (legacy versions supporting APEX 20K). According to the Altera APEX 20K datasheet, the device supports Passive Serial configuration from a serial EEPROM and JTAG in-system programming via the IEEE 1149.1 boundary-scan interface. Quartus II versions after 13.0 do not support APEX 20K.

Where do I find the EP20K100CQ208C9 pinout?

The EP20K100CQ208C9 pinout for the 208-pin PQFP package is published in the Altera APEX 20K datasheet, which lists each of the 208 pins by number with signal name (user I/O bank, JTAG, configuration, power, ground). The package uses standard PQFP pin numbering starting at pin 1 on the dot marker, proceeding counter-clockwise around the package body.

Where can I download the EP20K100CQ208C9 datasheet PDF?

The official EP20K100CQ208C9 datasheet is the Altera APEX 20K Device Family datasheet, available as a PDF download from the Intel FPGA documentation archive (formerly altera.com/literature). Search for the APEX 20K datasheet PDF, which covers all package and speed-grade variants including the C9 speed grade in PQFP-208.

How does EP20K100CQ208C9 compare to a modern Cyclone IV FPGA?

The EP20K100CQ208C9 (1999-era APEX 20K) at 100K gates is roughly comparable in logic density to a modern Cyclone IV EP4CE6 or EP4CE10, but the Cyclone IV offers lower core voltage (1.2 V vs 1.8 V), more Block RAM, dedicated DSP blocks, and active production status. For new designs, choose Cyclone IV or Cyclone 10 LP instead of the obsolete APEX 20K.

When should I choose EP20K100CQ208C9 over a modern FPGA?

Choose the EP20K100CQ208C9 only when maintaining pin-compatibility with a legacy board design or replacing an obsolete APEX 20K in fielded equipment. For new designs, the obsolete status of the APEX 20K family means long lead times and uncertain supply - modern Cyclone IV, MAX 10, or Lattice ECP5 FPGAs offer better cost, power, and toolchain support for new projects.

What is the best drop-in replacement for the EP20K100CQ208C9?

The best drop-in replacements for the EP20K100CQ208C9 in the same 208-pin PQFP package are the speed-grade variants EP20K100CQ208C8ES and EP20K100CQ208C7ES from the same APEX 20K family. These share identical pinout, package, and die but offer different speed grades, enabling direct PCB-level substitution when C9 stock is unavailable.

What is the operating temperature range of EP20K100CQ208C9?

The EP20K100CQ208C9 operates across a commercial 0 C to +70 C temperature range as indicated by the C in the part number. For industrial (-40 C to +85 C) applications, you would need an I-grade variant - check whether Altera offered an EP20K100QI208I9 or equivalent for harsh-environment designs.

What are the key specifications of EP20K100CQ208C9 that engineers should know?

The key specifications of the EP20K100CQ208C9 are: 100,000 typical gates, 4,160 logic elements, 26 embedded system blocks, 53,248 RAM bits, 4 PLLs, 159 user I/O, 208-pin PQFP package, 0.18 micron CMOS SRAM process, 1.8 V typical core supply, and commercial 0 C to +70 C operating temperature with C9 speed grade timing.

選定ガイド

Choose the EP20K100CQ208C9 when you need the highest speed grade in the APEX 20K 100K-gate family and your design operates in commercial 0 to 70 C temperature. Drop down to EP20K100CQ208C8 for designs with relaxed timing margins (typically 10-15% Fmax reduction), or EP20K100CQ208C7 for the lowest-cost sourcing when timing is non-critical. All four variants share the identical 208-pin PQFP footprint and die, so PCB layout remains unchanged. For new designs, however, prefer a modern Cyclone IV or Lattice ECP5 with active production status, lower core voltage, and current toolchain support.

設計ノート

The APEX 20K core operates at 1.8 V (VCCINT) while I/O banks use VCCIO at 2.5 V, 3.3 V, or 5 V depending on interface standard. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a bulk 100 uF tantalum or aluminum polymer capacitor near the device to handle inrush current during configuration. The configuration bitstream load typically draws 50-100 mA peak, so regulator headroom matters.

Use a continuous ground plane on layer 2 directly under the PQFP-208 device to provide a low-impedance return path for the 4 PLL outputs and high-speed I/O. Route DCLK and DATA0 configuration signals as a matched-length pair (within 100 mil) to avoid configuration failures. Keep PLL analog supply pins (VCC_PLL) isolated with a ferrite bead from digital VCCINT to minimize jitter.

Do not attempt to use Quartus II versions newer than 13.0 - APEX 20K device support was removed. Legacy MAX+PLUS II 10.2 or Quartus II 13.0 are the last tool versions that target this family. JTAG chain must include the EPC configuration device as the first device in the chain if both are JTAG-programmed, otherwise boundary-scan can corrupt the FPGA's configuration memory.
